TPS2490: Can the hot-swap-controller be used for bi-directional currents

Hi Nick,

Do you want to have overcurrent protection on both the directions. ?

In general, the body diode of the hot-swap MOSFET allows current flow from Vout to Vin side. After a while, the Vin gets charged and enhances the FET. Is this acceptable ?

Can you share your system block diagram, end application and product details.

Best Regards, Rakesh

Hi Rakesh,

Thanks for your answer! 

The point of this is, we're using the HSC (hot swap controller) to protect the system for inrush currents. On this system there are motors which could provide regenerative braking if the HSC's allow for it. 

I'm not quite sure a bidirectional protection truly is necessary but the HSC should allow for bidirectional current for as long as the regenerative braking lasts in the most ideal case. 

I hope this answers your question

But it will not trip anything in the HSC to switch it off for a bit right? 

We could not have any kind of moment where there is no forward current the moment that the regenerative braking is stopping. 

yes. It will not trip in reverse direction.

Thank you for your help, we will order some and do some definitive tests but this already helps us a lot!
